摘　　要：重点概述了近年来流线模拟计算在流线轨迹追踪、流体运移计算和油气藏工程应用3个方面的突出进展。第一,指出流线追踪的根本在于速度场的逼近,从速度场逼近多项式、网格细化、特殊区域处理3个方面出发,评述在地质构造复杂的油气藏中提高流线追踪精确性和计算效率的方法;第二,指出传统流线模拟方法在传质方程计算中的局限,评述其在可压缩流体、非牛顿流体等运移问题中的进展;第三,指出流线模拟的特色在于高效计算和流场识别,并介绍了其在油藏经营管理中的典型应用。Based on the calculation process of streamline simulation,this paper summarizes the outstanding progress of this method in streamline trajectory tracking,fluid migration calculation and reservoir engineering application in the past 15 years.(1)It is pointed out that the essence of streamline tracing lies in the approximation of velocity field.The methods to improve streamline tracing accuracy and calculation efficiency in oil and gas reservoirs with complex geological structure are reviewed starting from three aspects of velocity field approximation polynomial,mesh refinement and special area processing.(2)The limitation of traditional streamline simulation method in the calculation of mass transfer equation is pointed out,and its progress in the study of compressible fluid and non Newtonian fluid migration is reviewed.(3)It is pointed out that the characteristics of streamline simulation lie in efficient calculation and flow field identification,and the typical applications of streamline simulation in reservoir management are introduced.
